TechSpike - Substra for federated ML

[r-casula]

We should start putting together a POC for the FN integration with Substra to trigger ML jobs. Ideally we would need to do it in an outbound connection only fashion, possibly leaning on what normal tasks will do (if substra allows to integrate with this model)

Considerations for evaluating the ML frameworks:

• Deployment
• Support
• Dependencies
• Security
• Bonus Features
• Domain specificity
